My invention relates to improvements radio attachments for phpnographs.

It has become common practice 'to employ the sound amplifying horns of phonographs to amplify sounds from the different radio receivingiinstruments. Some of the methods of application of said instruments to phonograph horns involve the mutilation thereof and the resultant sacrifice in the resonance of the horn. Other methods of application result in rendering the usually artistic' cabinets unsightly in appearance and are often attended with laborious manipulation required to convert the phonograph mechanism for use in connection with radio equipment and in adapting it again to normal use.

An object of my invention; is to provide a simple attachment for phonographs, which is easily applied thereto, without undesirably affecting the artistic features thereof, and which maybe easily and quickly operated to alternately adapt the phonograph amplifier for use with the sound producing means of the phonograph and with such means of another device;

More specifically it is my object to provide, in a device of the present nature, a movable mounting common to the sound producing devices of a phonograph and a radio receiving set, the movement of saidmounting serving to selectively bring said devices into communication with the phonograph amplifier and serving further, in either case,v to modify the volume of sound, as may be desired.

With the foregoing and other objects in view, which will appear in the following descri tion, the invention resides in the ,novel com ination and arrangement of parts and in the details of constructidn hereinafter described and claimed.

In the drawings, Fig. 1 is a diagrammatical view in vertical, central section, illustrating a conventional phonograph and my improve attachment applied thereto; Figs. 2 and 3 are views illustrating a portion of the top of the cabinet body and showing the converter slide, in plan, in different positions and Fig. 4 is a vertical sectional view in detail taken on the line 4-4 of Fig. 3.

Referring to the drawing, A indicates the cabinet of a conventional phonograph, the

same having the ordinary sound amplifying horn 10 registering at its receiving end with RADIO ATTACHMENT FOB PEONOGRAI'ES. i

an opening 11 in the head piece or motor board 12. Instead of fixedly mounting the usual hollow base 13 of the phonograph tone dat d November as, 1924,'Ser1a1 no. 628,358,11 April 2, 1m. 511mm 7 i for reissue filed January 28,1928. Serial m. 88,381.

arm on the head piece 12 in position covering the opening 11, I supply a special mounting therefor. This mounting comprises a plate or slide 14 having beveled side edges slidably in terlocked with correspondingly ibeveled uides 15. Said slide is formed with openings 16 and 17 therethrough, the opening )6 being arranged V to rest in full registration with the opening 11 in the head piece 12 when the slide 14 is moved to its extreme right position (Figs. 3 and 4) with the right end thereof against a stop or abutment 18.

The opening17 in said slide is arranged'to fully register with said opening 11, when the slide 14 occupies extreme left position Figsl 1 and 2) with the left end thereof aga stop or abutment 19 The base 13 of the tone arm is mounted on the slide 14 so as to coverv the opening 17 and a loud speaking radio rece1ver 20 or other sound conducting instrument is mounted on said slide so as to cover the opening 16. In using the phonograph, the slide 14 occupies the position shown in Figs. 1 and 2, wherein the tone arm of the phonograph is brought into communication with the born 10, said horn being converted to use in connection with the radio speaker 20 by merely shifting the slide 14 to the right and thereby bringing the radio instrument into com munication with said horn. Thus, it will be understood that the user, by a simple thrust of the slide 1 1, can employ the horn 10 as an amplifier for the phonograph or for other associated sound reproducing means. It will also be understood that adjustment of the slide restricting registration of the openin 16 and 17 with the opening 11 will modif the volume of sound issuing from the horn 10. Changesin the specific form of my inven- 1 tion, as herein disclosed, may be made within msta the scope of what is claimed without departing from the, spirit of my invention.

What is claimed is: 1. {The combination with a phonograph including the usual amplifying horn and hollow tone arm base and also with a radio sound producing instrument, of a slide supplying, a, mounting for said base and instrument, said slide traversingthe receivin end of said horn and having opemngs t erethrough arranged to severally register with ing being movable to selectively guide said openings into registration with the receiving end of said horn.

3. The combination with a phonograph including the usual amplifying horn and hollow tone arm base and also with 'a radio sound producing instrument, of a mounting for said'base and instrument, said mounting having openings therethrough, one for communication with said base and one for communication with said instrument, the mounting being movable to selectively guide said openings into registration with the receiving end of said horn and opposed abutments to stop said mounting in positions acquirin full registration of said openings with sai end-of said horn.

4. .Th e combination with a phonograph including its amplifying horn and tone arm "and also with a radio sound producing instrument, of means mounting said tone arm and instrument for simultaneous movement whereby either said tone arm or said instrument may be moved into communication with said horn and theother moved out of communication with said horn.

5, The combination with a phonograph ineluding its amplifying horn and tone arm and also with a radio sound producing instrument, of a unitaryzsupport for said tone arm and said instrument, said support being movable to selectively bringeither said tone arm or said instrument into communication with said horn.

6. The combination with a phonograph including 'its amplifying horn and tone" arni and also with a radio sound producinginstrument, of a member movab y mounted with respect to the amplifying horn and mechanically connected to move said tone arm and instrument whereby said tone arm and instrument may be selectively brought into communication with said horn by the movement of said member. I

7. In combination with a cabinet, a sound amplifier mounted on the'cabinet, a sound conducting member, an electrical sound producing instrument, and a unitary support for said member and said instrument movably mounted on said cabinet, said support being movable rectilinearly to selectively bring said member or said instrument into operative relation with said amplifier.

"8. The combination with a phonograph, having an amplifying horn'and a. tone arm, and an electrical sound producing instrument, of a support for said tone arm and instrument, said sup ort being rectilinearly movable to selective y bring either said tone arm or said instrument into communication with said horn.

- 9. In combination, a cabinet, a sound amplifying horn immovably mounted on the cabinet, a member mounted on the cabinet, a

sound conduit onsaid member, and an electrical sound producing instrument on said member, said member being movable to selectively bring either said sound conduit or said instrument into operative relation with said horn.

10. The combination with a phonograph including a stationary amplifying horn and a movably mounted sound instrument and tone arm movably mounted above the motor board, of rectilinearly slidable means adapted to severally guide said tone arm' and instrument into communication with said horn.

In testimony whereof I have signed this specification.
